在你html文件的<head>与</head>之间加上:
<STYLE>
.spanstyle {
position:absolute;
visibility:visible;
top:-50px;
font-size:10pt;
font-family:Verdana;
font-weight:bold;
color:black;
}
</STYLE>
<script>
var x,y
var step=20
var flag=0
var message="中华网网络教室"
message=message.split("")
var xpos=new Array()
for (i=0;i<=message.length-1;i++) {
xpos[i]=-50
}
var ypos=new Array()
for (i=0;i<=message.length-1;i++) {
ypos[i]=-50
}
function handlerMM(e){
x = (document.layers) ? e.pageX : document.body.scrollLeft+event.clientX
y = (document.layers) ? e.pageY : document.body.scrollTop+event.clientY
flag=1
}
function makesnake() {
if (flag==1 && document.all) {
for (i=message.length-1; i>=1; i--) {
xpos[i]=xpos[i-1]+step
ypos[i]=ypos[i-1]
}
xpos[0]=x+step
ypos[0]=y
for (i=0; i<message.length-1; i++) {
var thisspan = eval("span"+(i)+".style")
thisspan.posLeft=xpos[i]
thisspan.posTop=ypos[i]
}
}
else if (flag==1 && document.layers) {
for (i=message.length-1; i>=1; i--) {
xpos[i]=xpos[i-1]+step
ypos[i]=ypos[i-1]
}
xpos[0]=x+step
ypos[0]=y
for (i=0; i<message.length-1; i++) {
var thisspan = eval("document.span"+i)
thisspan.left=xpos[i]
thisspan.top=ypos[i]
}
}
var timer=setTimeout("makesnake()",30)
}
</script>
把你html文件的<body>部分改为:
<BODY onLoad="makesnake()" style="width:100%;overflow-x:hidden;overflow-y:scroll">
把下面代码加入你html文件<body>和</body>之间:
<script>
for (i=0;i<=message.length-1;i++) {
document.write("<span id='span"+i+"' class='spanstyle'>")
document.write(message[i])
document.write("</span>")
}
if (document.layers){
document.captureEvents(Event.MOUSEMOVE);
}
document.onmousemove = handlerMM;
</script>
